Setup
Before we implement any smelting recipes, we’ll create a little class in which we’ll use to register them. We’ll call this class ModRecipes, following the same convention as our ModItems and ModBlocks classes. We’ll put this into the recipe package inside our main package so if we have to implement more complex custom recipes, we’ll have a place to group them together.
You’ll want an empty init static method in ModRecipes which is where we’ll register our recipes in just a moment.

package net.shadowfacts.tutorial.recipe;
public class ModRecipes {
public static void init() {
}
}
The ModRecipes.init method should be called from TutorialMod#init. The init method is called during the initialization phase which occurs after the pre-initialization phase. We want to register our recipes here instead of in the pre-init or post-init phases because all mod items/blocks (including those from other mods) should be registered at this point.

Smelting Recipe
The furnace recipe we’ll add is going to be a simple 1 Copper Ore to 1 Copper Ingot recipe. All this requires is 1 call to GameRegistry.addSmelting in our ModRecipes.init method:

public static void init() {
GameRegistry.addSmelting(ModBlocks.oreCopper, new ItemStack(ModItems.ingotCopper), 0.7f);
}
GameRegistry.addSmelting takes 3 parameters, the item/block/stack input, the ItemStack output, and the amount of experience to be given to the player (per smelt).
